This paper shows FMCW radar using MIMO VAA. Polyphase codes are designed for modulating the successive chirps of transmitting signals. The codes are optimized to have low cross-correlations regardless of the Doppler filter mismatch. Compared with orthogonal codes, the designed codes show robust performance for Doppler mismatch and lower angle estimation errors. The entire procedure is explained, and the simulation results are provided.<\/jats:p>","DOI":"10.3390\/rs14112595","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:30:06Z","timestamp":1653964206000},"page":"2595","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["MIMO FMCW Radar with Doppler-Insensitive Polyphase Codes"],"prefix":"10.3390","volume":"14","author":[{"given":"EunHee","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Defense System Engineering, Sejong University, 209 Neungdong-ro, Gwangjn-gu, Seoul 05006, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1090","DOI":"10.1049\/iet-rsn.2018.5075","article-title":"Random phase code for automotive MIMO radars using combined frequency shift keying-linear FMCW waveform","volume":"12","author":"Kim","year":"2018","journal-title":"IET Radar Sonar Navig."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"276","DOI":"10.1109\/TAP.1986.1143830","article-title":"Multiple emitter location and signal parameter estimation","volume":"1","author":"Schmidt","year":"1986","journal-title":"IEEE Trans.
